Abstract
Abstract A tensioning and compression apparatus is disclosed for systems for laminating facing on insulation mats and for coiling the laminate. The system includes a powered roll around which the blanket is coiled and a tensioning and compression roll which engages the exterior surface with a force in a direction toward the powered roll which can be maintained at a constant level during any coiling operation or changed as a function of the diameter of the roll during the coiling operation. Force on the tension and compression roll is provided by a piston and cylinder actuator supplied with related positive pressures to both ends of the cylinder. The relationship between the two pressures determines the output force of the cylinder and the force applied by the tension and compression roll to the coil being formed. Separately adjustable control circuits are provided to supply the pressure to each end of the cylinder.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
177 words
A tensioning and compression apparatus for use in the production of rolls of faced insulation blankets, comprising a frame, a powered roll journaled on said frame for rotation about a first axis and around which a blanket is coiled, a tension and compression roll supported on said frame for movement toward and away from said powered roll and journaled for rotation about a second axis substantially parallel to said first axis, a piston and cylinder actuator mounted on said frame and connected to said tension and compression roll operable to apply a force to said tension and compression roll as a blanket is being coiled on said powered roll, said actuator producing a controlled force of engagement between said tension and compression roll and the outer surface of the blanket being coiled on said powered roll, and pressure control means connected to supply a separately controlled positive pressure to each of the two ends of said cylinder, said force of engagement being a function of the relationship between the positive pressures being applied to said cylinder ends.
